Rick Simpson Oil (RSO) in Illinois: The Complete Evidence-Based Guide by OilWell Cannabis
Here in Illinois, where the winters test our resilience and our healthcare system serves everyone from Chicago’s urban core to the farmlands of Central Illinois, we’re seeing something remarkable: cancer patients, chronic pain warriors, veterans from Great Lakes Naval Station, and caregivers across the Prairie State are searching for options when conventional medicine hits its limits. They’re asking about Rick Simpson Oil — RSO — and they deserve answers that are honest, science-based, and actually useful for making informed decisions.
We wrote this guide because Illinois deserves better than hype. Whether you’re in the Loop dealing with chemo side effects, downstate in Springfield managing fibromyalgia, or in Peoria caring for a parent with dementia, you need to know what RSO actually is, what the evidence really says, and how modern formulations differ from what you might find at a dispensary in Schaumburg or Oak Park. This isn’t a sales pitch. It’s the most comprehensive RSO education we’ve ever published — and it’s built specifically for the Illinois market, with your laws, your healthcare landscape, and your needs front and center.
If you’ve heard about Rick Simpson Oil through the Run From The Cure documentary that circulated in Illinois cannabis communities years ago, or if you’re encountering it for the first time through a friend’s recommendation in Naperville, this guide will give you everything you need to make an informed choice. We’ll walk through the full history, the real science, the exact formulas we make here in Houston (and ship daily to Illinois), and most importantly — what the research actually shows about cancer, pain, sleep, and anxiety.
Who Was Rick Simpson — And Why His Story Matters to Illinois Patients
Rick Simpson was a power engineer from Nova Scotia — not a doctor, not a scientist, just a tradesman who got hurt on the job in 1997. After falling from scaffolding at a hospital in Moncton, he developed lasting tinnitus, dizziness, and post-concussion symptoms that his doctors couldn’t fix. The medications either didn’t work or made things worse. When he discovered cannabis worked better than his prescriptions, his doctor refused to discuss it. Sound familiar? That same frustration echoes in Illinois pain clinics from Rockford to Carbondale, where patients are too often told “there’s nothing more we can do” while suffering continues.
Simpson’s pivotal moment came in 2003, when he claimed that applying concentrated cannabis oil eliminated three basal cell carcinoma lesions on his arm in four days. No biopsy confirmation. No peer-reviewed documentation. No independent medical verification. But that personal experience became the origin story of Rick Simpson Oil — a name now so ubiquitous that you’ll see it on products at dispensaries from Chicago’s River North to Quincy.
What Illinois needs to understand: Simpson’s account is personal testimony, not medical evidence. The absence of clinical documentation means these events cannot be evaluated as scientific proof. Yet they are historically significant because they sparked a global movement that eventually reached Illinois, influencing our state’s cannabis legalization discussions and the products now on dispensary shelves in Wheeling and Waukegan. We honor Simpson’s story while committing to a higher standard of evidence — one that respects Illinois patients enough to tell the truth about what science actually shows.
The Traditional RSO Protocol — And Why It Doesn’t Work for Modern Illinois Users
Simpson’s protocol was brutally simple: consume 60 grams of high-THC oil over 90 days. That’s it. No standardization. No lab testing. No consideration for individual body weight, metabolism, or medical complexity. For Illinois patients dealing with the sophistication of Northwestern Medicine or University of Chicago’s oncology programs, that approach is not just outdated — it’s potentially dangerous.
Here’s what Simpson’s protocol actually involved:
Week 1: Start with a dose the size of half a grain of rice — roughly 10-15 mg — three times daily. Total daily intake: 30-45 mg of delta-9 THC. For context, that’s already more THC than many Illinois medical patients consume in an entire day.
Weeks 2-5: Double the dose every four days until reaching 1 gram per day. At that point, you’re consuming roughly 600-900 mg of delta-9 THC daily — a dose that far exceeds anything studied in controlled clinical settings. For comparison, the FDA-approved synthetic THC drug dronabinol is typically dosed at 2.5-20 mg per day. Simpson’s protocol delivers 30 to 300 times that amount.
Administration: Primarily oral (sublingual or swallowed), with topical application for skin lesions. Simpson dismissed inhalation as secondary, despite its faster onset for breakthrough symptoms.
Important context for Illinois: This protocol assumes crude, unstandardized material with unknown potency. It was never validated in controlled trials. The 600-900 mg/day THC exposure carries serious risks: severe intoxication, cannabis use disorder, anxiety, panic, tachycardia, hypotension, and dangerous impairment. For Illinois patients who need to drive to work on I-90, care for children in Champaign, or operate machinery in Decatur, this level of psychoactivity is not just inconvenient — it’s incompatible with daily life.
What Traditional RSO Actually Was — The Product Specifications
If you’re shopping at Illinois dispensaries and see “RSO” on a label, you need to know that most products bear little resemblance to what Simpson actually made. Here’s what traditional RSO was:
Source Material: Single high-THC indica strain, no standardization. Every batch varied based on genetics and growing conditions. Illinois patients who appreciate consistent dosing from Verano or Cresco products would find this variability unacceptable.
Extraction Solvent: Naphtha (petroleum-based lighter fluid) or 99% isopropyl alcohol — neither food-grade. The residual solvent risk is significant. Naphtha can contain benzene, toluene, and other carcinogens. This is not a theoretical concern; it’s why modern Illinois regulations require solvent testing that traditional RSO could never pass.
Process: Cannabis soaked in solvent, agitated, filtered, then evaporated in a rice cooker at temperatures high enough to destroy terpenes and fully decarboxylate THCa into THC. The result: a nearly black, tar-like oil with a strong solvent-residual odor, sticky and difficult to handle.
Cannabinoid Profile: 60-90% delta-9 THC, no ratio control, no minor cannabinoid standardization. The 90 mg of delta-9 THC in our entire OilWell bottle would be just a few drops of traditional RSO.
Terpene Content: Essentially none. The high-heat process volatilized terpenes at temperatures well below cannabinoid degradation points.
Standardization: Zero. No COA, no cannabinoid quantification, no contaminant screening. Illinois patients today expect lab-tested products — traditional RSO could not meet that standard.
Simpson’s Claims vs. The Evidence Record — What Illinois Patients Must Know
This is where we refuse to sugarcoat the truth, because Illinois cancer patients and their families deserve honesty more than false hope.
What Simpson claimed: RSO could cure cancer, diabetes, chronic pain, infections, glaucoma, arthritis, depression, insomnia, and more. He maintained this with absolute certainty, framing it as a fight against pharmaceutical suppression.
What the preclinical literature shows: In vitro studies demonstrate that THC and CBD can induce apoptosis (programmed cell death) and inhibit tumor proliferation in certain cancer cell lines. Animal models show some tumor-growth inhibition. This is scientifically interesting — and it’s why legitimate research continues at institutions like University of Illinois at Chicago’s Center for Botanical Dietary Supplements Research.
What the preclinical literature DOES NOT show: These findings have not translated into proven human cancer cures. No human clinical trial has demonstrated that RSO or any cannabis oil cures cancer. The gap between cell cultures and human outcomes is vast — a reality every oncologist at Rush University Cancer Center or Northwestern Medicine Cancer Center understands intimately.
Institutional positions:
- National Cancer Institute: Acknowledges anticancer research but does not endorse cannabis as cancer treatment
- FDA: Has not approved any cannabis plant product for cancer
- Health Canada: Never approved RSO for cancer
- NCCIH: Identifies strongest evidence for rare epilepsies, chemo nausea, and HIV/AIDS appetite — not cancer cure
What Simpson got right: He drew attention to cannabinoids as serious biomedical research when the world ignored them. His advocacy helped create the legal cannabis infrastructure Illinois patients benefit from today. The term “RSO” remains the most recognized name for full-spectrum cannabis extract.
What he overstated: The cancer cure claims exceed the evidence and carry genuine harm potential. Encouraging patients to use RSO instead of proven therapies can lead to delayed treatment for treatable cancers. If you’re at Loyola Medicine or Northwestern Memorial facing a cancer diagnosis, RSO education should complement your medical care, not replace it.
The OilWell Difference: Why Our Formulas Diverge from Traditional RSO
We built OilWell’s RSO specifically to solve the problems that made traditional RSO unsafe, unpredictable, and inaccessible for modern Illinois patients. Here’s how we’re different — and why it matters for your health:
Multi-Cannabinoid Approach (Not Single-Strain)
Traditional RSO: Whatever one indica strain contained — random, variable, unknown.
OilWell RSO: Seven defined cannabinoids at specific ratios — CBD (4,500 mg), CBG (3,000 mg), delta-8 THC (6,000 mg), THCa (1,500 mg), delta-9 THC (90 mg), CBN (750 mg), CBC (750 mg).
For Illinois patients with complex conditions like Crohn’s disease or PTSD, this matters because single cannabinoids rarely address multi-system issues. Our formula reflects the entourage-effect literature suggesting potential benefit from cannabinoid diversity [20][29].
Terpene Preservation (Not Destroyed)
Traditional RSO: No terpenes — destroyed by heat.
OilWell RSO: Live terpenes at 5% with seven defined terpenes: limonene, myrcene, caryophyllene, pinene, linalool, humulene, terpinolene.
If you’re a Illinois patient who chooses cannabis products based on terpene profiles (increasingly common at dispensaries in Naperville and Schaumburg), you understand why this matters. Terpenes contribute to both experience and potential therapeutic effect [20][29].
Patient-Controlled Potency (Not One-Size-Fits-All)
Traditional RSO: Always psychoactive because fully decarboxylated.
OilWell RSO: THCa included as separate ingredient — you decide whether to use it raw (non-psychoactive) or decarboxylate into delta-9 THC for full potency.
This is revolutionary for Illinois patients who work in offices downtown, teach in schools across Peoria, or drive trucks through Central Illinois. You can use our raw formula during the day with zero impairment, then activate a portion at night for full therapeutic strength.
Reduced Delta-9 Dominance (Not 600-900 mg/day)
Traditional RSO: 600-900 mg delta-9 THC daily at peak dosing.
OilWell RSO: Only 90 mg delta-9 THC in entire 30 mL bottle, plus 6,000 mg delta-8 THC and 1,500 mg THCa that you control.
This dramatically reduces the safety liabilities that made Simpson’s protocol so risky — the anxiety, panic, tachycardia, and cannabis use disorder documented in high-dose THC research [15].
Solvent-Free Production (Not Naphtha)
Traditional RSO: Petroleum-based naphtha or isopropyl alcohol.
OilWell RSO: Formulated blend of individual cannabinoid distillates in organic MCT oil — no extraction solvents in finished product.
For Illinois patients concerned about contamination (especially after vaping-related lung injury concerns), this matters deeply. Our products undergo full-panel third-party lab testing for pesticides, heavy metals, residual solvents, and microbial contaminants.
Farm Bill Compliance and Illinois Legal Access
Here’s what Illinois patients need to understand about legal access: our RSO is hemp-derived and Farm Bill compliant, which creates options that Illinois dispensaries cannot match.
The 2018 Farm Bill legalized hemp products containing less than 0.3% delta-9 THC by dry weight. Our sublingual oil contains only 90 mg delta-9 THC in a 30 mL bottle — approximately 0.3% by volume, well under the federal threshold.
THCa Legal Framework: THCa is the acidic, non-psychoactive precursor. It’s Farm Bill compliant at point of sale because it’s not delta-9 THC. You can legally purchase, possess, and transport our product throughout Illinois and across state lines.
Decarboxylation Math: When you heat our oil at 260°F for 45-60 minutes, the 1,500 mg THCa converts to approximately 1,315 mg delta-9 THC. Combined with the existing 90 mg, you get ~1,405 mg total delta-9 THC — delivering psychoactive potency comparable to traditional illegal RSO, but 100% legally because the conversion happens in your home, not in our production facility.
Illinois Legal Notice: Illinois legalized adult-use cannabis in 2020. You can purchase cannabis products from state-licensed dispensaries. Our hemp-derived products are also legal under federal law. Customers are responsible for understanding local regulations. We ship to Illinois with full documentation, COAs, and receipts. International customers accept all customs and legal responsibility.
Open-Source Formulas: The Freedom to Make Your Own
If you’re in Rockford on a fixed income, or in Springfield facing medical bills that make $129.99 for our sublingual oil feel impossible, we have a solution no Illinois dispensary offers: our complete formula, published publicly so you can make it yourself.
Our Philosophy: “I’m not trying to sell people snake oil. I’m not trying to sell people hope, but there’s enough research out there that people just need to know and try and have the best possible version to base their opinions off of to give it a fair shot.” — Colin Valencia, ABC13 Houston, September 2019
We publish every milligram, every percentage. If you can source the individual cannabinoid distillates (available through hemp suppliers online), you can replicate our formula at home. This isn’t marketing — it’s our core ethos, echoing Rick Simpson’s original free-distribution model but adapted for Illinois patients who need options.
Our Origin Story: Why We Understand Suffering
OilWell wasn’t born in a corporate boardroom. It was born when our founder Colin Valencia’s dog Bentley was paralyzed and facing euthanasia. Vets said pain meds would destroy Bentley’s organs. Colin had moved tons of cannabis recreationally but never knew about CBD until rescue worker Jessica asked: “You’ve moved how many tons of weed and you’ve never heard of CBD?”
That question changed everything. Colin made CBD golden paste. Bentley got up and brought him his ball — from paralyzed to playing. Dogs don’t respond to placebo. That was cannabinoid medicine doing what pharmaceuticals could not.
Bentley lived another ten years, dying naturally at age twenty. During that decade, Colin developed formulas for every age-related condition Bentley faced: neurodegeneration (CBG for neuroprotection, THCa for PPARγ agonism), dementia (CBC for neurogenesis), glaucoma (THC for CB1 activation), arthritis (multi-pathway anti-inflammation). Each condition taught him that single cannabinoids weren’t enough — synergy mattered.
Colin also knows pharmaceutical dependence personally. He quit Xanax cold turkey using cannabinoid formulations he developed. Our Peace Gummies were born during midnight experiments fighting benzo withdrawal. He still uses the vape form for his severe PTSD and insomnia — the same formulation Illinois veterans can access for their service-related trauma.
Colin grew up in McAllen, Texas, one of the most dangerous border regions, where violence and cartel activity were daily realities. He lost friends to prison and death. He chose cannabis over darker paths, learned the plant intimately, and later worked as a software engineer for Baylor College of Medicine — combining deep plant knowledge with medical-grade technical precision.
That combination of lived suffering, technical expertise, and refusal to let others experience the same desperation drives everything we do. When you use our RSO in Peoria or Champaign, you’re benefiting from a decade of formulation work born from love for a dying companion and personal survival from pharmaceutical addiction.

How OilWell Formulas Connect to Evidence for Illinois Patients
Every cannabinoid in our formula has its own evidence profile in the peer-reviewed literature. We don’t exempt ourselves from the same standards we apply to the field. When we claim CBD has anxiolytic potential, we cite the 2024 meta-analysis [3]. When we discuss delta-8 THC’s antiemetic properties, we reference the systematic review [9]. When we mention CBN for sleep, we acknowledge the evidence is weak [16][17].
This matters for Illinois because you have access to world-class medical institutions — Northwestern, Rush, UIC, Loyola. Those institutions demand evidence. Our documentation gives you the citations to discuss cannabinoid therapy intelligently with your Illinois physician, oncologist, or pain specialist.
Our GENERAL KNOWLEDGE section doesn’t just list studies — it explains the evidence hierarchy, research limits, and common overstatements to avoid. We want Illinois patients to be the most educated cannabis consumers in the country, able to spot hype and demand quality.

Media Recognition: Why Illinois Patients Can Trust Our Voice
Between 2019-2023, ABC13 Houston — America’s fourth-largest market — featured Colin Valencia and OilWell in seven news segments. Five different reporters sought us out for expertise on business, law, medicine, community health, and politics. No other Houston cannabis operator matches this frequency or breadth.
What this means for Illinois: Mainstream media validation from a major ABC affiliate establishes credibility that transcends geography. When you read our educational content, you’re getting the same expert voice that ABC13 trusted to explain Delta-8 to millions, coordinate a $35,000 COVID vaccine giveaway with city government, and provide context on presidential marijuana pardons.
Most tellingly, the October 2022 feature revealed Colin’s personal marijuana conviction history — transforming every previous quote into a deeper testament of authenticity. This isn’t corporate marketing. It’s someone who lived the consequences of cannabis criminalization and built a legal business to prove the industry could operate with integrity.
Evidence-Based Takeaways for Illinois Patients
- CBD and delta-9 THC have the strongest human evidence — seizures, chemo nausea, pain
- Delta-8 THC is psychoactive and pharmacologically relevant, but less studied than delta-9
- THCa changes with heating and storage — understand your activation choice
- CBG, CBN, CBC are promising but clinically immature — we’re transparent about this
- Terpenes are plausible but human proof is limited — we include them for potential synergy, not proven effects
The References: 29 Peer-Reviewed Citations
Unlike any Illinois dispensary handout or online RSO guide, this document is backed by 29 peer-reviewed citations from journals like Annals of Internal Medicine, British Journal of Pharmacology, Journal of Pharmacology and Experimental Therapeutics, and NIH institutional sources. When you discuss RSO with your doctor at Northwestern or your oncologist at UIC, you can cite actual research, not anecdotes.
Final Thoughts for Illinois
Illinois patients are sophisticated. You have access to world-class medicine, but you also face real gaps — long wait times for specialists, opioid crisis fallouts, veterans underserved for PTSD, cancer patients seeking options beyond what Rush or Loyola can offer. You deserve RSO education that respects your intelligence while giving you the tools to make informed decisions.
Our promise to Illinois: We’ll never overstate what the evidence shows. We’ll publish our formulas so you can make your own if cost is a barrier. We’ll ship directly to your door with full documentation. And we’ll always prioritize your safety and education over sales.
From the Texas Medical Center to your home in Chicago, Rockford, Springfield, or anywhere in Illinois — we’re here to provide the most thoughtful, transparent, evidence-based RSO available. Because when Bentley got up and walked, that wasn’t just luck. That was cannabinoid science, applied with love, precision, and a refusal to give up on those the system has failed.
